Thumpers and Cable Fault Location
-
Cable testing can be broken down to different steps of the process, starting with a time domain reflectometer test to look for an incident signal on the line or, in some high resistance situations, VLF testing. These tests will identify a fault, allowing you to move on to pre-locating it. In some low resistance faults this will occur alongside the identification via the TDR.

Low Resistance Or Continuity Testing
-
From Megger, these highly accurate, easy to operate instruments measure resistance with resolution as fine as 0.1 micro-ohm. Digital micro-ohmeters and DLROs measure contact resistance of switch and circuit breakers, aircraft frame bonds, and rail and pipeline bonds just to name a few of the applications. Megger has models available for testing using test currents from 0.5 mA to 200 amps covering a multitude of applications that require precise low-resistance measurements.

Static Electric Motor Analyzers
-
Baker Instruments’ static motor test equipment is the industry-leading suite of products for detecting weaknesses and faults in the insulation systems of electric motors, generators and coils. Employing both low-voltage and high-voltage tests – such as Baker’s signature surge test - these essential troubleshooting and predictive maintenance tools allow maintenance professionals to assess any need to maintain or replace specific motors and generators that support their business. Equally at home in the motor repair shop or on a plant floor, these testers ensure that the electrical condition of your rotating machinery is understood.

Cable Fault, Test And Diagnostics
-
Allows an operator to test twisted pair cables for faults without physically disconnecting the cables from the switch.

Primary Injection Test Systems
-
Primary current injection testing is utilised in high current/high voltage scenarios found at large electrical installations such as substations. A large current (between 100A and 20,000A depending on system specifications and test requirements) is injected directly on the primary side of the electrical system such as a circuit breaker. The objective of the test is to identify how the system operates under various levels of current load.

Turns Ratio Testing
-
The transformer turns ratio test, or TTR test, confirms that the transformer has the correct ratio of primary turns to secondary turns. Using this test correctly can help to identify tap changer performance, shorted turns, open windings, incorrect winding connections and other faults inside transformers. Megger’s range of TTR testers are robust to withstand the harsh conditions that some transformer testing in. The range includes varying features to simplify and speed up testing as well as 3 phase TTR testers and PT and CT TTR testers.

Partial Discharge
-
Is a localized dielectric breakdown (DB) (which does not completely bridge the space between the two conductors) of a small portion of a solid or fluid electrical insulation (EI) system under high voltage (HV) stress.

AC Insulation Testing
-
AC insulation tests are a popular response to the increasingly demanding industrial, power and domestic marketplaces. Insulation materials have had to become more efficient to keep up with demand; more efficient equipment requires less insulation material to meet the minimum acceptable value of insulation resistance. In turn, cables have become smaller and lighter. However, under certain higher stress testing conditions such as DC testing, cables like Crossed Linked Polyethylene (XLPE) can quickly degrade.

Contact Resistance Test Sets
-
When a high current passes through a pair of mechanically independent metallic contacts, the resistance must be as low as possible. An increase in resistance can lead to additional degradation, as I2R losses will cause local heating of the contact surfaces. Our range of micro-ohmmeters measure both steady state and dynamic low resistance values. With test currents up to 600A available, logging and trending are also available on some models. We ensure that our Contact Resistance tests sets are portable, making them suitable for field measurements. Our contact resistance testers’ portability makes them ideal for a vast range of resistance testing across the entire LV, MV HV and EHV spectrum.

Ground Testing
-
Ensuring an effective earth system is essential in a telecommunications system, and Megger is expert in earth testing having been there right from the start. These days Megger offers top end systems for design and soil surveys as well as tough easy to use testers for field engineers. We have tried to make the testers self checking as much as we can, to allow you to concentrate on collating and understanding the results.

Cable Fault and Test System Vans
-
Whether you are working on-site, in the countryside or an urban environment, having the right equipment available when conducting fault location operations is vital. When the correct tools can be accessed easily, fault-location time speeds up dramatically, and faults can be dealt with more efficiently. Megger’s range of cable test vans offer solutions to the challenges of fault location in the real world, no matter the environment. Our test van systems have been developed in collaboration with end users to ensure that they live up to the standards of daily fieldwork. Our vans are designed to be adaptable to the end users needs so that the most appropriate tests may be carried out for the cable in question, regardless of whether it is low, medium or high voltage.
